'We sent 10,000 copies of a useless calendar to a client': 20+ People who are face-palming over their coworkers' mistakes

Every job requires you to have coworkers, whether you want to or not. These people encountered some coworkers who made extra dumb mistakes — and some are more dangerous than others. 

The r/AskReddit community answered the question, "What's the dumbest mistake you've seen an incompetent coworker make?" And I am shocked at some of the answers. People wrote in from all walks of life, from lawyers to pet shop workers to designers.

Everyone makes mistakes, but some people don't handle that well. It seems like a lot of the stories stem from people either not caring about their job, or making careless mistakes and then lying about it. That just makes things worse in the long run — for that person, and for the coworkers that need to clean up the messes.
